Lines: 26 I have recently written a "color editor" for X that allows the user to "mix" colors using various different color models (rgb, cmy, hls, hsv), but what I really want to do is create an interactive palette that would allow the user to mix colors in a manner similar to an artist mixing paints on a palette. I found a reference to "tristimulus values" for colors and how a mixture of colors can be calculated from their respective "tristimulus" values based upon proportions. But, there was no explanation for determining tristimulus values from what I am accustomed to working with: machine rgb values. Can some of you graphics/physics/color gurus out there shed some (white) light on the issue of color mixing? You can send me email, or post a reply. Thanks. ************************************************************************* **** Michael Flanery, Systems Engineer **** **** **** Mips Computer Systems **** **** **** (Dallas Field Office) **** "Shave the cheetahs" **** **** 214-770-7979 **** **** **** flanery@mips.com **** **** *************************************************************************
